Analysis on Genetic Diversity of Casuarina equisetifolia Provenances by RAPD
利用RAPD分子标记对35个短枝木麻黄(Casuarina equisefifolia)种源的遗传多样性和亲缘关系进行了分析.15个随机引物共扩增了出201条DNA带,其中148条为多态性带,占73.63%,平均每个引物扩增出9.9条多态性带.种源的Shannon’s多样性指数为0.435 4,Nei’s基因多样度为0.288 4,表明短枝木麻黄种源的遗传多样性水平较高.35个种源彼此的遗传距离在0.088 4~0.753 9之间,平均0.404 5,经过UPGMA聚类分析将35个种源划分为A、B、C ...

Abstract Hadrosaurid dinosaurs are generally regarded as “crested” or “non‐crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non‐crested” hadrosaur is known to have possessed a soft tissue cranial crest (or comb), based on an exceptionally preserved “mummified” specimen. Here we redescribe this specimen and

Abstract Belonostomus longirostrisis was named for an isolated jaw fragment from freshwater Upper Cretaceous (Campanian) sediments of the Dinosaur Park Formation of Alberta, Canada. Following the description of the Albertan species, numerous isolated cranial and postcranial elements have been collected from the Dinosaur Park Formation and assigned to B.

Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Variabilité génétique de l'Okoumé. Essais de provenances et de descendances
Dans le but de l'amélioration génétique de l'okoumé (Aucouméa klaineana, Burseracée, on a comparé des plantations de provenances les plus diverses et de descendances variées, au Gabon en 1967, 1975 et 1976. Il semble qu'il n'y ait pas de différence entre

Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...
